Running script and the Strategy Analyzer

[GKonheiser]

I am currently running the Strategy Analyzer and want to continue working on another script but when I enable another Strategy it keeps switching itself off. Is this normal behaviour as the Analyser is running?

Hello GKonheiser,

Thank you for your note.

In general, you should be able to enable another strategy while running the Strategy Analyzer. Do you receive an error on screen? Are there errors on the Log tab of the Control Center? If so, what do these errors report?

I look forward to your response.

Ya I see it. Its an error running my script.

Error on calling 'OnBarUpdate' method for strategy 'PivotTrader/090cbfc51f4247be961c84b3ad775753': PivotTrader.DrawLine: startTime must be greater/equal the minimum date but was 01-Jan-01 12:00:00 AM


This is the code,

protected override void OnBarUpdate()
{
if(CurrentBars[1] == 0)
return;

if (Bars.FirstBarOfSession)
Bars.Session.GetNextBeginEnd(BarsArray[1], 1, out sessionBegin, out sessionEnd);

// Calculate Pivot Points

pp = (Highs[1][1] + Lows[1][1] + Closes[1][1])/3;

DrawLine("pp" + CurrentBars[1], false, sessionBegin, pp, sessionEnd, pp, Color.Red, DashStyle.Solid,1);

Print("Session Start: " + sessionBegin + " Session End: " + sessionEnd + pp);


Should I post it in the Programming forum for help?

Hello GKonheiser,

Thank you for your response.

This may not be a programming item. How far back does the Strategy go in real-time or on the Strategy Analyzer? Further back then 2001?

I look forward to your response.

[GKonheiser]

Im applying the strategy to the FGBL 12-09 contract.

Hello GKonheiser,

Thank you for your response.

On the Strategy Analyzer what is the From date set to under time frame?

When enabling your strategy on the Strategies tab of the NinjaTrader Control Center, what is the Days To Load set to?

I look forward to your response.

[GKonheiser]

Strategy analyser from 7th Dec 07 and Days to load is 735 on the chart.

Hello GKonheiser,

Thank you for your response.

What Session Template is being used for the strategy?

Can you attach your code to your response so I may investigate this matter further?

You will find your strategy located in the following directory on your PC: (My) Documents\NinjaTrader 7\bin\Custom\Strategy

If you prefer you can send your strategy to support[at]ninjatrader[dot]com with 'ATTN: Patrick - 938891' in the subject line and a reference to this thread in the body of the e-mail: http://www.ninjatrader.com/support/f...ad.php?t=61520

Hello GKonheiser,

Thank you for your response.

I am unable to reproduce this behavior. To clarify on your steps here you are backtesting the strategy on the FGBL 12-09 but attempting to run it in real-time on the FGBL 12-13 correct?

Please provide all necessary steps to re-create this item.

[GKonheiser]

Sorry if I was unclear. I am running the optimizer on one Script from dec 07 to dec 09 and I'm working on a second script applying to a chart of 2 year of data. But it doesn't matter what I apply the second strategy too, as long as the optimizer is running it automatically disables the strategy.

[NinjaTrader_PatrickH]

Hello GKonheiser,

Thank you for your response.

I see the same behavior when running a backtest and then enabling my strategy on the Strategies tab, however this only occurs if I click to enable the strategy and then click within the Strategies tab on the Control Center even on a different region of the window.

For this not to happen you would need to click outside the Control Center window after checking the option for enable on the strategy.

I will investigate this matter further on my end and follow up with you on any additional information I have.
